Isobutyryl chloride → N-{3-[2,3-Dimethoxy-6-(1-oxo-indan-4-yl)-phenoxymethyl]-oxetan-3-ylmethyl}-isobutyramide

Participants

Reaction Steps

To a stirring solution of 4-[2-(3-Aminomethyl-oxetan-3-ylmethoxy)-3,4-dimethoxy-phenyl]-indan-1-one (Compound 191) (150 mg, 0.3916 mmol) in dichloromethane (15 mL), were added diisopropylethylamine (50 mg, 0.390 mmol) and isobutyryl chloride (41 mg, 0.391 mmol) and the resultant reaction mixture was stirred at RT for 2 h. The reaction mixture was diluted with water and extracted with dichloromethane (3×). The combined dichloromethane layer was washed with brine, dried over anhydrous sodium sulphate and concentrated under reduced pressure. Purification by column chromatography (silica gel, 0-2% methanol in dichloromethane) afforded the title compound as a solid.
